System

Abstract

A system comprises: a vehicle capable of running by unmanned driving; an inspection facility having a roller to rotate while supporting a wheel of the vehicle; a first sensor that detects the position of the vehicle; a second sensor that detects the position of the vehicle, the second sensor detecting the position of the vehicle with higher accuracy than the first sensor; and a controller that acquires position information about the vehicle using at least one of the first sensor and the second sensor and controls the vehicle using the position information. The controller acquires the position information using the first sensor if a condition set in advance including a provision that the vehicle be over the roller is not fulfilled, and acquires the position information using at least the second sensor if the condition is fulfilled.

What is claimed is: 
     
         1 . A system comprising:
 a vehicle configured to be able to run by unmanned driving;   an inspection facility having a roller configured be able to rotate while supporting a wheel of the vehicle;   a first sensor configured to detect the position of the vehicle;   a second sensor configured to detect the position of the vehicle, wherein the second sensor is configured to detect the position of the vehicle with higher accuracy than the first sensor; and   a controller configured to acquire position information about the vehicle using at least one of the first sensor and the second sensor, wherein the controller is configured to control the vehicle using the position information, wherein the controller is configured to acquire the position information using the first sensor when a predetermined condition including a provision that the vehicle be over the roller is not fulfilled, wherein the controller is configured to acquire the position information using at least the second sensor when the predetermined condition is fulfilled.   
     
     
         2 . The system according to  claim 1 ,
 wherein the predetermined condition further includes a provision that the rotation speed of the wheel or the rotation speed of the roller be equal to or greater than a predetermined rotation speed.   
     
     
         3 . The system according to  claim 1 ,
 wherein the predetermined condition further includes a provision that a degree of unevenness of the position of the vehicle detected by the first sensor be equal to or greater than a predetermined degree.   
     
     
         4 . The system according to  claim 1 ,
 wherein the controller is configured to acquire the position information using the first sensor and the second sensor when the predetermined condition is fulfilled, and   wherein the controller is configured to change a contribution of the first sensor and a contribution of the second sensor to the position information in response to the rotation speed of the wheel or the rotation speed of the roller when the predetermined condition is fulfilled.   
     
     
         5 . The system according to  claim 1 ,
 wherein the controller configured to acquire the position information using the first sensor and the second sensor when the predetermined condition is fulfilled, and   wherein the controller configured to change a contribution of the first sensor and a contribution of the second sensor to the position information in response to a degree of unevenness of the position of the vehicle detected by the first sensor when the predetermined condition is fulfilled.
